Hi every one
i have a 3d array with dimension 51*71*3 and i want to obtain column vector 153*1
d=(51*71*3)
n=d(:,:,1) so now 51*71
r=d(:,:,2) becomes 51*71
c=data(:,3) becomes51*71
so now b=[n;r;c] 153*71
but i need153*1 instead
how can i obtain this vector
thanks in advance

x = rand(51, 71, 3);
v = reshape(x(:, 27, :), [], 1);
size(v)
ans = 1×2
153 1

@RADWAN A F ZEYADI The random vector was just to generate sample data of the same size as your problem. Jan is not suggesting that you need to use rand( ) in your code. E.g., using your d variable:
v = reshape(d(:, 27, :), [], 1);
